Hi
my device with the
VID = 0x28e9
PID = 0x028a
should be supported by the cp210x driver. But in fact this VID and PID does
not appear.
Why do you think this driver should support this device?
See the output:
alias: usb:v3195pF190d*dc*dsc*dp*ic*isc*ip*in*
alias: usb:v2626pEA60d*dc*dsc*dp*ic*isc*ip*in*

The manufacturer recommends to use the driver maintained in the linux
kernels.
Which driver exactly? Do you have a link to that recommendation?
thanks,

This device announces itself as a HID device so should
not be handled by any usb-serial driver.
